The objective was to evaluate the microbiological quality of water in the province of Tucumán during the first half of 2008. We analyzed 257 samples of water using sampling techniques and formal identification of indicators of microbiological contamination (APHA). Of the samples tested represented a 45.14% rivers and streams, to 3.89% of industrial water, groundwater to 1.56%, 4.67% to water for irrigation and 44.74% for water samples analysed drinking. The results allowed for a clear distinction between the, water quality analysis for drinking which was presented as superior to the original surface. Regardless of origin, there was a significant degree of pollution associated with the presence of coliform bacteria. When comparing the values obtained with data from previous studies carried out in the same half of 2007, there was no significant variations between the two periods, except the determination of E. coli in river water from 2008 that showed a decrease of almost 30%. This study shows the importance of microbiological control of water to improve the availability and quality of this essential resource for all aspects of life.
